LatencyMon
The best thing about LatencyMon is the fact that it will offer you a real-time audio suitability checker which can easily measure DPC and ISR execution times. It will also provide you with detailed information about the system. This app has been designed to analyze your computer and provide you with details about overall latency.
The data will be relevant for the users who need to process real-time audio signals on their computer.
It is essential to analyze the potential causes and take preventive measures, and this is why this tool will help you when it comes to performance issues. This tool will allow you to perform the test and also view the results with a minimum effort.
You will only have to run the application and start monitoring. You will manage to view the results in the main window. LatencyMon will offer you access to system performance, and it will also record the kernel time latencies. It is also an excellent tool because it will calculate the highest execution time for the interrupt service or deferred procedure calls. It is an easy to use software application, but if you want to read the results, you will need to be an experienced user.
The tool will offer you a brief interpretation, and you will need to consider this interpretation to improve the performance of your PC. I will also show all of the running processes and installed drivers and even CPU core statistics. These details can be exported to text files. It will be pretty easy to select the processor cores and adjust the test parameters in the Options window.
LatencyMon will come in handy when the user wants to avoid clicks and pops in the audio output.
Latency monitor windows 10
Latest version: LatencyMon v 7.00
LatencyMon checks if a system running Windows is suitable for processing real-time audio and other tasks. LatencyMon analyzes the possible causes of buffer underruns by measuring kernel timer latencies and reporting DPC and ISR execution times as well as hard pagefaults. It will provide a comprehensible report and find the kernel modules and processes responsible for causing audio latencies which result in drop outs. It also provides the functionality of an ISR monitor, DPC monitor and a hard pagefault monitor.
LatencyMon will display the highest latencies of a kernel timer and report the highest execution times of ISR and DPC routines as well as hard pagefaults. In most cases it will also find the drivers and processes responsible for executing them. It will create a comprehensible report which also displays all sampled data in a detailed manner allowing you to perform in-depth analysis.
The audio latency problem
Windows is not a real-time operating system. All requests to the operating system are delivered on a best effort basis. There are no guarantees whatsoever that requests are delivered within a certain time frame, which are the characteristics of a real-time operating system. That is not a problem for most devices and tasks but this is bad news for audio applications (which are considered soft real-time) because they need to deliver data to the subsystem and the hardware in buffers several times per second. If one or more buffers miss their deadlines and are not delivered in time it has audible consequences which are recognized as dropouts, clicks and pops.
About DPCs and ISRs
The Windows thread dispatcher (also known as scheduler) which is part of the kernel executes threads based on a priority scheme. Threads with higher priority will be given a longer execution time (also known as quantum or time slice) than threads with a lower priority. However the kernel also knows other types of units of execution known as interrupt service routines (ISRs). Devices connected to the system may interrupt on a connected CPU and cause their interrupt service routines to execute. An interrupt can occur on the same processor that an audio program is running on. Any thread that was running on the processor on which an interrupt occurred will be temporarily halted regardless of its priority. The interrupt service routine (ISR) is executed and may schedule a DPC (Deferred Procedure Call) to offload an amount of work. The DPC will most likely run immediately on the same processor which means the audio application will halt until both the ISR and the DPC routines have finished execution. That is because ISRs and DPCs run at elevated IRQL which means they cannot become preempted by the thread dispatcher (scheduler). Therefore to guarantee responsiveness of the system, ISR and DPC routines should execute as fast as possible. Guidelines say that they should not spend more than 100 µs of execution time however this is often not reached due to hardware factors beyond the control of the driver developer. If execution time gets too high, the audio program may be unable to deliver audio buffers to the hardware in a timely manner.
About hard pagefaults
Windows uses a concept of virtual memory which relies on the page translation system provided by the CPU. Whenever a memory address is requested which is not available in physical memory (not resident), an INT 14 will occur. The OS provided INT 14 handler will decide how to proceed next. If the page in which the address resides is known to Windows but not resident, Windows will read in the required page from the page file. That is known as a hard pagefault and can take a lot of time to complete. If the page can be read in from the hard disk cache, the price will be limited. However if it needs to physically read in the data from disk sectors this takes a lot of time. If an audio program hits a hard pagefault while it is playing it will almost certainly have audible consequences recognized as dropouts, clicks or pops.
Hard pagefaults are a very common but often overlooked cause of audio dropouts, clicks and pops. They especially occur often with audio software that uses a lot of memory such as samplers. Solutions for avoiding hard pagefaults are increasing the working set of the audio application, increasing the amount of RAM or disabling the pagefile altogether. Note that if you disable the pagefile, the system may run «out of memory» because it does not have the pagefile available to swap memory to. Also the system will no longer create crash dump files in case of a system crash.

LatencyMon русская версия
Когда компьютер лагает, выдает баги, а звуки заметно проедают или отстают (например, во время процесса прохождения игры), то на первый взгляд может показаться, что проблема кроется в соединении с интернетом. Это не всегда так. Бывает, что лаги появляются от системных ошибок. Чтобы удостовериться в этом и просто мониторить задержки всех процессов, была создана утилита LatencyMon. Бесплатно скачать последнюю версию приложения на русском языке вы сможете в самом конце странички.
Описание и возможности
LatencyMon – это приложение, предназначенное для анализа системы, позволяющее определить, насколько ваш ПК способен воспроизводить музыку и звуки без регулярных сбоев. Да-да, первоначально утилита предназначена для определения причин искажения звуков. Назовем главные функции софта:
- В первую очередь LatencyMon помогает проверять, способна ли текущая версия Windows принимать потоковое аудио.
- В режиме реального времени программа не только обнаруживает просадки, но и указывает в отчетах процессы и драйвера, которые влияют на задержку.
- Софт также измеряет задержки таймера ядра в случае, если системные компоненты показывают разное время загрузки.
Как пользоваться
В этом разделе мы расскажем, как установить программу на ПК пошагово с поясняющими скриншотами, а также о том, как пользоваться LatencyMon.
Загрузка и установка
Итак, вот подробная инструкция по установке:
- Файл загрузки находится чуть ниже на этой странице, кликните на скачать. Распакуйте архив и запустите файл-инсталлятор.
- Как это обычно бывает, после запуска мастера установки пользователю необходимо принять лицензионное соглашение. Поставьте флажок на указанный на скриншоте пункт и кликните на «Next».
- Выберите расположение целевого каталога, если требуется. Если хотите оставить все как есть, нажмите на «Next».
- Все, что остается сделать – это дождаться окончания загрузки.
Инструкция по работе
Этот инструмент предназначен для профессионалов и продвинутых пользователей, которым требуются полные отчеты, помогающие юзерам найти процессы, вызывающие задержки звука. Управление интуитивно понятное: значок зеленого треугольника запускает анализ, красный квадрат – приостанавливает его.
Для начала рекомендуется провести тест со всеми выключенными приложениями. Если проблем нет, то следует запустить ту программу (или требовательную игру), во время которой случались просадки. В случае, если проблема обнаружится и показатели будут выше 500 нс, то в скобках будет указан драйвер, вызвавший просадки. Чтобы проанализировать работу таймеров CPU, нажмите на CPU-Z. В этой вкладке будет подробно расписана вся информация о процессоре. Чтобы запустить таймер, перейдите в раздел Tools, а затем – Timers. В идеале все таймеры покажут одинаковое время.
Достоинства и недостатки
Итак, давайте же разберем позитивные и отрицательные стороны программы по сравнению с аналогичным софтом:
- Тестирование операционной системы на предмет различных задержек.
- Предоставление полных и понятных отчетов.
- Автоматическое определение параметров DCP и ICR.
- Несмотря на простой интерфейс, новичку точно будет сложно разобраться: в утилите очень много вкладок и отчетов о работе системы. Тут не сразу разберешься, что к чему.
- Отсутствие русского языка.
Похожие приложения
Рассмотрим еще несколько подобных программ, способных отслеживать задержки и выдавать отчеты о работе системы:
- Process Explorer 16.32.
- Process Hacker 2.39.
- ManicTime Portable 4.6.3.0.
- CPU Monitor and Alert 4.1.
- Windows Inspection Tool Set 3.2.3 (32-бит).
Системные требования
- Центральный процессор: более 1ГГц.
- Оперативная память: от 1 Гб ОЗУ.
- Пространство на жестком диске: от 10.6 Мб.
- Платформа: Microsoft Windows 32 или 64-бит.
